litespeed may restart to fix 503 error automatically.
in a site with buggy php script, this may be helpful without whole site down.

Usually when i got an 503 error and LS was restarted, i got an e-mail notification. Why i didn't get any notification?

Is there any log that i can check to see why it happened?
I tried to open "Server Log Viewer" but there are too many.
